7 · ⟨Aëtius⟩: intellect and soul
I.48.7 · Wachsmuth pp. 317
Pythagoras, Anaxagoras, Plato, Xenocrates, and Cleanthes hold that intellect enters from outside.
Parmenides, Empedocles, and Democritus hold that intellect and soul are the same; on their account, no living creature would be irrational in the strict sense.1243
8.1 · Iamblichus: the development of reason
I.48.8.1 · Wachsmuth pp. 317-318
From Iamblichus, from On the Soul.
Again, then, concerning intellect and all the soul’s higher powers, the Stoics say that reason is not implanted at once, but is assembled later from perceptions and impressions, at about fourteen years of age. The followers of Plato and Pythagoras, however, say that reason is present even in the newborn, though it is obscured by external things and does not exercise its proper activity, but lies quiet.1244
8.2 · Two intellects in Peripatetic accounts
I.48.8.2 · Wachsmuth pp. 318
Now, then, [concerning intellect,] many Peripatetics posit one intellect arising from seed and from nature, as sprouting immediately from the first generation. They say that another, separable and summoned from outside, arrives very late, when the potential intellect has reached completion and is suitably disposed to participate in actual thinking.1245
8.3 · Intellect entering with the soul
I.48.8.3 · Wachsmuth pp. 318
Many of the Platonists themselves also bring intellect in together with soul at its first entrance into the body, and hold that soul and intellect are not distinct from one another at all.1246
